Visitors

As it gets closer to my due date I have started thinking about who I want to visit in the early weeks and who I think should wait a few weeks. My partner and I both agreed that only immediate family (siblings and parents) should visit within the first 2 weeks as we a first time parents and my partner is one of 5 kids. Followed by extended family 2 weeks later then friends a following week later. I informed my parents of this and they have hit the roof saying how dare I deny my grandparents the chance to come to the hospital to see me and my son after I give birth. My nanna is currently in hospital herself after fracturing her colar bone falling off a chair. Has anyone else been in this situation before and how did you deal with it?
